Digital product approvals were conceived, created, and maintained by Engineering Express.  This product evaluation is the first in history to have a digitally assisted counterpart as part of the evaluation document.  It complies with F.S. 553.8425 and 61G20-3 that permit modifications to a product evaluation if certified by a professional engineer.  Digital content also expands the understanding, research, ordering, and understanding of related parts and accessories for the product.

FS 553.8425 (3):
Local building officials may accept modifications to approved products or their installations if sufficient evidence is submitted to the local building official to demonstrate compliance with the code or the intent of the code, including such evidence as certifications from a Florida registered architect or Florida professional engineer.

Information regarding the necessity of listing all extrusions and material specifications was brought to the FL POC at their August 14, 2018 meeting. It was concluded by the POC that the level of information listed on submittals such as the digitally assisted approval are within statutory compliance.  Click here for information on that meeting
